#2403 new Bug

Inactive sea-ice component in the BENCH test case

Reported by: smueller Owned by: systeam

Severity: minor Keywords: BENCH, SI3

Description

Context

The sea-ice component in the BENCH test case remains inactive (nn_ice = 0) despite definition of key_si3.

Analysis

When key_si3 is defined, the sea-ice component would automatically be activated (nn_ice = 2) in the release-4.0-HEAD version of NEMO. In the trunk version, the source code corresponding to this automatic activation in model setups without AGRIF (source:/NEMO/trunk/src/OCE/SBC/sbcmod.F90#L130) has been commented out since r12377; in configurations with AGRIF the corresponding automatic setting of nn_ice remains in place.

Fix

The explicit activation of the sea-ice component (nn_ice = 2) should be included in the namelist_cfg_orca*_like files supplied for the BENCH configuration in source:/NEMO/trunk/tests/BENCH/EXPREF. Also, the explicit setting of nn_ice in the reference configurations with active sea-ice component should be verified.

Further, the deactivation of the key_si3-dependent automatic sea-ice activation should be explored; if such deactivation is not required, reintroduction of the inactive code at source:/NEMO/trunk/src/OCE/SBC/sbcmod.F90#L130 could be considered.
